Abstract：
Duraplasty is one of the most common neurosurgical procedures which complications include iatrogenic pseudomeningocele, which is common, but ossification of pseudomeningocele following cranial surgery is a rare event. We present a case of a 2-year-old male patient who came to our hospital with a huge bulge in his head and weakness in the right arm and leg. He had a history of sagittal craniosynostosis with a postoperative cranioplasty complication of left parital pseudomeningocele. He underwent a duraplasty, but the bulge recurred with failed cerebrospinal fluid aspiration and external ventricular drain, changing in size periodically. Computed tomography showed that the bulge was a median and left paramedian parital encephalocele, so encephalocele with ossification was diagnosed and a cranioplasty was done. This case highlights that iatrogenic encephaloceles with ossification can develop after duraplasty repair in the parital region. Also, if a postoperative pseudomeningocele changes in size or consistency, clinicians should look for ossification.
摘要：
胸膜成形术是最常见的神经外科手术之一，其并发症包括医源性假性脊膜膨出，这是常见的，但是颅骨手术后假性脑膜膨出骨化是罕见的事件。我们介绍了一例2岁的男性患者，他来到我们医院时头部有巨大的隆起，右臂和腿部无力。他有矢状位颅骨前突病史，并伴有左顶假性脑膜膨出的颅骨成形术并发症。他做了硬脑膜成形术,但是由于脑脊液抽吸和外部脑室引流失败，隆起复发，定期改变大小。计算机断层扫描显示，隆起是正中和左侧的副正中性咽部脑膨出，因此诊断出骨化脑膨出并进行了颅骨成形术。此病例强调了骨化的医源性脑囊肿在耳部区域的硬脑膜成形术修复后可以发展。此外，如果术后假性脑膜膨出的大小或一致性发生变化，临床医生应该寻找骨化。
